Alba Thermal Springs and Spa

At 282 Browns Rd in Fingal, at the southern tip of the Mornington Peninsula, Alba draws geothermal water from 500 metres underground and routes it through a spread of indoor, open-air, and outdoor pools before filtering it and returning it to the same aquifer. That closed loop is worth knowing about. The water is genuinely geothermal, the infrastructure is purpose-built around it, and the site sits within native coastal bushland with accommodation up in the dunes above.

The pool circuit runs from a falls pool at around 36 degrees up to thermal pools at roughly 42 degrees along the top of the main water feature and at rooftop level. A dry sauna with Nordic-inspired wood panelling, a plunge pool, and a fire pit round out the bathing options. Botanical and rain pools are part of the spread as well. Temperatures for individual pools beyond the falls pool and the upper thermals aren’t published in detail, but visitor accounts point to a clear progression between the cooler and hotter ends.

The water comes from a 500-metre-deep aquifer, gets filtered, and is reheated to the temperature it was extracted at before going back into use. That’s a different thing from most of what calls itself a thermal spring in Australia.

The treatment spa runs a full menu, covering everything from massage and facials to Vichy Immersion and Hammam Float, with guided meditation and DIY workshop options alongside the full- and half-day packages. The architecture draws consistent comment from visitors: concrete-heavy and futuristic, with large double-glazed panels and LED lighting set against well-kept native gardens.

On-site, Thyme restaurant serves a Mediterranean-style menu built around locally-sourced seasonal produce. A kiosk patio adjacent to Thyme runs lighter fare from 11am to 3pm. The restaurant can back up during busy periods, which is worth keeping in mind if you’re working to a schedule.

Visitors arriving from interstate and overseas have described it as world class. That’s not a claim that comes up often in reviews of Australian hot springs, and a 4.2 rating across more than 2,000 Google reviews broadly supports it.

A Springs Club membership is available for regulars, though the specific terms aren’t publicly listed. Accommodation up in the dunes makes an overnight stay straightforward if you want to take your time.

Alba opens at 7:00am daily and runs until 10:00pm, closing only on Christmas Day. Booking ahead is sensible. The better sessions fill, and this is a large, well-regarded destination. The address is 282 Browns Rd, Fingal; phone (03) 5985 0900.
