The single supplement is one of cruising's least-discussed inequities — a surcharge that can quietly double the cost of a solo cabin and price out travellers who simply don't have a partner to share with. For Australians over 50, particularly women travelling alone, knowing which lines have genuinely reformed their solo pricing and which are still applying 200% penalties is the difference between a rewarding journey and an expensive lesson. This guide names names, compares real policies and gives readers the tools to push back.
What Is a Single Supplement and Why Does It Matter?
A single supplement is the extra charge a cruise line applies when one person occupies a cabin priced for two. The logic, from the line's perspective, is revenue protection — they lose the second fare. For the solo traveller, the effect is blunt: pay significantly more per night than a couple in the identical cabin, for the same ocean view and the same bowl of soup at dinner.
For women over 50 travelling alone — whether widowed, divorced, or simply preferring their own company — this surcharge can be the deciding factor between booking and walking away. A 200% single supplement on a AUD 3,000 twin-share fare means a solo traveller pays AUD 6,000 for the same 7 nights. That's not a minor administrative fee. It's a structural pricing decision that some lines are beginning to rethink, and others are not.
The percentage itself varies wildly and is rarely front-and-centre on a cruise line's website. It's buried in fare conditions, sometimes described as a 'solo occupancy rate' rather than a supplement — language that softens what is, in effect, a penalty for travelling without a partner. Knowing the real figure before you start comparing itineraries is the first practical step.
Viking Ocean Cruises: The Benchmark for Solo Fairness
Viking has done more than any other premium cruise line to address solo pricing in a meaningful way. On select sailings, Viking designates a number of cabins as true solo occupancy at no supplement — the same per-night rate a person in a twin cabin would pay. These aren't converted storage rooms. On Viking Ocean ships, the solo cabins are compact but properly designed, with the same quality fittings and veranda access that defines the broader fleet.
The catch — and there is one — is availability. Solo cabins sell quickly, and the no-supplement inventory is limited. Viking's model works best for travellers who plan six to twelve months ahead. For those who book late, a solo supplement of around 50% may apply on remaining cabin categories, which is still considerably more reasonable than industry standard. Confirm current allocation directly with Viking's Australian reservations team rather than relying on the website.
Viking's included fare model also removes a separate source of solo travel anxiety: there are no obligatory gratuities on Viking Ocean, and many sailings include a drinks package, shore excursions and flights in the advertised price. For a solo traveller budgeting carefully, an all-inclusive headline fare is easier to compare honestly than a lower sticker price with a long list of add-ons. Indicative solo fares for a 7-night European sailing start from around AUD 4,500 in shoulder season — confirm current pricing directly.
Princess Cruises: The Supplement Exists, but So Does the Negotiation
Princess Cruises operates one of the largest fleets calling at Australian ports, and its solo supplement policy is best described as variable. The standard published rate applies a 100% supplement — meaning a solo traveller pays the full twin-share cabin cost alone. On some cabin categories and itineraries, that climbs to 200%. There is no dedicated solo cabin category across the fleet.
What Princess does offer, quietly and inconsistently, is supplement waivers during shoulder season. These aren't advertised. They appear in trade promotions, sometimes in direct-booking offers, and occasionally when a reservations agent is asked directly about solo availability close to sailing. The lesson is straightforward: the website price is a starting point, not a final answer. A direct call to Princess Cruises Australia — not a third-party travel agent's website — is worth thirty minutes of anyone's time.
On the extras front, Princess operates a 'Plus' and 'Premier' fare bundle system that includes gratuities, Wi-Fi and drinks packages. For solo travellers, these bundles can represent genuine value because the per-person cost doesn't change based on cabin occupancy — you pay the bundle rate once, not twice. That said, the drinks package includes a daily alcohol allowance that not everyone will use, and the value calculation depends entirely on your habits. Read the inclusions carefully before assuming the bundle is cheaper than paying as you go.
P&O Cruises Australia: Budget Pricing with Budget Transparency
P&O Cruises Australia pitches itself as the accessible end of the market, and on twin-share pricing it largely delivers. A 7-night Pacific sailing from Sydney or Brisbane can be found from around AUD 1,200 per person in a twin-share interior cabin — indicative only, confirm current pricing. For solo travellers, however, P&O applies a supplement that typically ranges from 100% to 200% depending on cabin category, sailing date and availability. There are no designated solo cabins.
What you get for the lower base fare is a trade-off. P&O's ships are older than Viking's or Princess's newer vessels. The inclusive model is not in play — gratuities are charged daily per person (confirm current rates, as these change), and drinks, specialty dining and shore excursions are all additional. For a solo traveller, those daily gratuities are charged at the full single-occupancy rate, not halved. It adds up across a 7-night sailing in ways that aren't obvious from the headline fare.
P&O is worth considering for short domestic sailings where the solo supplement is waived or reduced through a last-minute deal — this does happen, particularly on 3–5 night cruises departing Sydney. For a longer solo journey, the total cost after supplement, gratuities and a drinks package may not be as competitive as the initial fare suggests. Run the full numbers before committing.
Coral Expeditions: Small Ships, Honest Pricing, Higher Base Cost
Coral Expeditions operates small expedition vessels along Australia's Kimberley coast, the Great Barrier Reef and Papua New Guinea — the kind of itineraries that attract culturally curious travellers who want genuine immersion rather than a floating resort. The solo supplement sits at around 150% on most sailings, which is better than the industry's worst but still a meaningful additional cost on an already-premium base fare.
The distinction with Coral Expeditions is what's included. Shore excursions, zodiac landings, naturalist guides and all meals are typically part of the fare. For a solo traveller who would otherwise be paying separately for every guided experience, the all-inclusive model changes the total cost comparison considerably. A 7-night Kimberley voyage at around AUD 6,000 solo — indicative, confirm directly — sounds steep against a P&O Pacific cruise, but the activity density is fundamentally different.
Coral Expeditions' smaller passenger numbers (typically under 120 guests) also create a social dynamic that solo travellers often find easier than a 3,000-person ship. Meals are communal, briefings are shared, and the guided nature of each day means conversation happens naturally. For a solo woman traveller who wants company without having to engineer it, that matters. Accessibility on expedition vessels varies — tender landings and zodiac transfers require reasonable mobility, and Coral Expeditions is candid about this in its pre-booking documentation.
The Fine Print: Gratuities, Drinks Packages and What Solo Travellers Actually Pay
Cruise lines present fares in ways that make direct comparison genuinely difficult, and solo travellers bear a disproportionate share of the add-on cost. Gratuities — sometimes called a 'service charge' or 'crew appreciation' — are charged per person per night on P&O and Princess if you choose a non-bundled fare. A solo traveller pays the full per-person rate with no partner to split it. Across a 7-night sailing, that can add AUD 150–200 to the total cost (indicative — confirm current rates with each line, as they adjust these figures regularly).
Drinks packages are sold per person per day. On Princess, the Plus bundle includes drinks, Wi-Fi and gratuities for a single per-person daily rate. For a solo traveller, this is the same rate a person in a twin cabin pays — so in that sense it's equitable. The question is whether you'll actually use it. If you drink wine at dinner and use Wi-Fi daily, the bundle is likely worth it. If you're a light drinker who'll use the ship's Wi-Fi once to check in with family, paying as you go may be cheaper. Viking's included model sidesteps this calculation entirely.
One line item that surprises many first-time cruisers is the onboard credit card hold. Ships place a pre-authorisation on your credit or debit card at embarkation — sometimes AUD 300–600 — to cover onboard spending. For solo travellers on a fixed income, this is worth knowing before you board. Confirm the hold amount with your cruise line and ensure your card has sufficient available credit beyond your actual spending budget.
A Checklist for Comparing Solo Cruise Quotes
Before accepting any published solo fare as final, use this checklist. First, confirm the exact single supplement percentage applied to your chosen cabin category — not the general policy, but the specific cabin on the specific sailing. Second, ask directly whether a supplement waiver or reduction is available for your travel dates, particularly in shoulder season. This question is worth asking even if the website shows no such offer. Third, calculate the total cost including daily gratuities (if not bundled), a drinks package appropriate to your habits, port taxes and any mandatory transfers. The headline fare and the total paid can differ by AUD 500–1,000 on a 7-night sailing.
Fourth, check whether the line's travel insurance offering covers pre-existing conditions — many cruise-line policies do not, and for travellers over 50, this is non-negotiable. Arrange independent travel insurance with medical evacuation cover and confirm the cruise line is named. Fifth, ask about the tender port policy: some ports require guests to board small boats to reach shore, and this is not suitable for all mobility levels. A ship's accessibility officer can advise which itinerary stops are tender-only. Sixth, if you're comparing an all-inclusive line (Viking, Coral Expeditions) against a à la carte line (P&O, Princess unbundled), build a like-for-like comparison that includes excursions, drinks and gratuities before deciding the cheaper headline fare is actually cheaper.
Finally, consider contacting a travel agent who specialises in cruises for mature-age travellers. They have access to group rates, solo-pairing programmes and shoulder-season supplement waivers that don't appear on public-facing websites. The Cruise Lines International Association (CLIA) maintains a directory of accredited cruise specialists in Australia — worth a look before booking directly.
Key takeaways
- Viking Ocean Cruises offers dedicated solo cabins with no supplement on select sailings — the clearest commitment to solo pricing fairness among premium lines.
- Princess Cruises and P&O apply 100–200% single supplements as standard, but shoulder-season waivers do exist and are worth asking for directly.
- Coral Expeditions charges around 150% for solo occupancy, but its all-inclusive model and small-ship social dynamic can make it better value than the supplement figure alone suggests.
- Gratuities and drinks packages are charged per person regardless of cabin occupancy — solo travellers should calculate these separately before comparing headline fares.
- The website fare is a starting point, not a contract: a direct phone call to reservations — especially outside peak season — regularly produces better solo pricing.
- A like-for-like cost comparison between cruise lines must include supplement, gratuities, drinks and excursions — the total paid, not the advertised fare, is the honest comparison.

Frequently asked questions
Which cruise lines offer true solo cabins with no single supplement for Australian travellers?
Viking Ocean Cruises offers dedicated solo cabins at no supplement on select sailings, making it the most straightforward option for Australian solo travellers over 50. Availability is limited and sells quickly, so booking six to twelve months ahead is advisable. No other major line currently calling at Australian ports maintains a permanent no-supplement solo cabin programme, though shoulder-season waivers are available on some Princess and P&O sailings if requested directly.
What is a fair single supplement percentage on a cruise?
A single supplement of 50% or less is considered fair — it acknowledges the line's revenue need without pricing solo travellers out of the market. Supplements of 100% mean you pay the full twin-share cabin cost alone, and 200% means you pay double. The industry average sits closer to 100–150%, though this varies by line, cabin category and season. Viking's no-supplement solo cabin is the current benchmark for fairness.
Do cruise lines ever waive the single supplement?
Yes, some cruise lines quietly waive or reduce solo supplements during shoulder season or when a sailing has unsold cabin inventory. These offers rarely appear on public websites — they're more often available through direct reservations calls or specialist cruise travel agents. Princess Cruises and P&O Australia are both known to offer supplement reductions closer to sailing dates. It's always worth asking specifically about solo supplement waivers when requesting a quote.
Are gratuities charged to solo travellers at the same rate as couples?
Yes. On cruise lines that charge gratuities separately — including P&O Australia and Princess Cruises on unbundled fares — the daily charge is per person, not per cabin. A solo traveller pays the same daily gratuity rate as each person in a twin cabin, with no reduction. Across a 7-night sailing, this can add AUD 150–200 to the total cost (indicative — confirm current rates with each line). Viking Ocean includes gratuities in its headline fare.
What should Australian over-50 solo cruisers know about travel insurance?
Travel insurance is essential and should be arranged independently rather than through the cruise line, as many cruise-line policies do not cover pre-existing medical conditions. For travellers over 50, ensure the policy includes medical evacuation cover, covers the full cruise region including any international ports, and names the cruise line explicitly. Declare all pre-existing conditions at the time of purchase — non-disclosure can void a claim. Compare policies through a licensed Australian insurance broker or comparison service.
