After two years of travel morsels and optimistic bookmarking, Australia is finally open for exploration once more. Sure, we’ve missed dining out and drinking at some of our favourite places, but there’s nothing like venturing into parts unknown. With the likes of the green labyrinths of the Adelaide Hills offering fine wine and fun, to the endless sandy beaches and clear-blue waters of the Eyre Peninsula, South Australia calls.

That’s made ever more helpful this month with the Great State Voucher scheme, which sees the Great State Voucher scheme offering up 60,000 Great State Experiences Vouchers to people across the country. From Monday March 7, the ballot will open for those looking to score up to $200 off hosted tours and experiences across the state.

With that in mind, here's six unique reasons to pencil in a trip to the southern state.

Experience a Coffin Bay oyster tour

Drive 30 minutes north-west from Port Lincoln and you’ll find the source of some of Australia’s most coveted oysters: Coffin Bay.

Visitors here can get to know the molluscs up close and personal with a farm tour. There’s a range of tour options here: a 90-minute boat ride through Kellidie Bay, home to many of the area’s oyster farms, is a great way to get a feel for it all; or for those willing to get a little wet, the three-hour Oyster Farm and Bay Tour takes you to a farm 16 kilometres out along Coffin Bay’s scenic waterways. Once there, you can throw on a pair of waders and saunter hip-deep through the aquafarm, sampling a few oysters along the way.

Swim with the sea lions along the Eyre Peninsula

The waters along the Eyre Peninsula are an aquatic feast teeming with marine life. If you’re lucky enough to visit between September and July, jump in a boat and set sail for one of the area’s sea lion spots.

The likes of Port Lincoln-based Calypso Star Charters offers eco-certified snorkelling tours around Hopkins, Langton, Grindal and Blyth islands, where you can frolic in the water with the sea pups. (Calypso also offers great white shark cage diving tours. Frolicking not advised).

Get up close and personal with lions at Monarto Safari Park

A one-hour drive east from Adelaide, Monarto Safari Park is home to one of Australia’s largest lion prides. The 1500-hectare open-range sanctuary is the largest safari park in Australia, and takes its role seriously as a protector and promoter of rare and endangered species. The Lions 360 Experience gives you access to the park’s extremely intimate 360-degree viewing cage, where lions roam freely just on the other side of the fence. As well as lions, the park is home to a range of African animals, including a crash of rhinos, a tower of giraffes, a coalition of cheetahs and mob of meerkats.

Eat, drink and admire at the d'Arenberg Cube

Set among lush mourvèdre grapevines in the McLaren Vale wine region is a building like no other.

The d'Arenberg Cube is a five-level, multipurpose space that includes d'Arenberg Winery’s tasting room, a casual restaurant, function areas and the Alternate Realities Museum, featuring contemporary art displays and a virtual fermenter.

D’Arenberg are offering their Wine Blending Bench at $190 for 2 pax. With the $100 GSV voucher, you pay $90.

Climb to the top of Adelaide Oval

You haven’t seen the city like this before. The Roofclimb Adelaide Oval experience takes you to the top of the iconic oval’s 50-metre-high roofline, for a 360-degree snapshot of Adelaide from above, with views stretching from the city’s coastlines to its vast foothills and beyond.

Standard tours include day, sunset or night climbs with a specially trained guide and the option to lean (yes, lean) over the edge of the stadium. The big-ticket attraction, though, is the Game On climb, which takes you up during an Adelaide or Port Adelaide AFL match and lets you watch a full quarter of play on the rooftop seats.

Glide over the Barossa Valley in a hot air balloon

Less than an hour’s drive from Adelaide, the Barossa Valley is one of Australia’s best-known wine regions, with idyllic towns dotted among picturesque vineyards and hills. Sure you can wind your way through its many trails and corners, but to really get a snapshot of this undulating wonderland, take an early morning hot air balloon ride.

Watch the sun rise as you soar above the Barossa ranges, then pick out a few wineries to visit later on. Barossa Balloon Adventures offer one-hour balloon rides year-round, with post-balloon breakfasts and sparkling wine. An elevated way to start your stay.
