Lucky Bay, Esperance, WA
Located in the picturesque Cape Le Grand National Park about one hour’s drive from Esperance, is the clear, turquoise waters of Lucky Bay. This remote beach is a prime spot for those who love swimming, snorkelling and fishing. Currently the campsite is being redeveloped and the beach is only open for day visits, but when you turn up to find the beach all to yourself (as is often the case, unless you count the western grey roos and pigmy possums in residence) you’ll be so glad you made the trek to this stunning, world-class piece of paradise. www.tourismwesternaustralia.com
Abraham Bosom Beach, Currarong, NSW
Hidden away behind the charms of Currarong (200km south of Sydney) and nestled under the impressive rainforest and sea cliffs of the Beecroft Peninsula, is this wonderful little swimming beach. While the conditions won’t set any surfer’s heart racing, this is a perfect place for the family (and pooch – it’s dog-friendly) to relax and frolic. Take the easy 2.5km bush walk in the headland to see the still visible remains of the wreck of the SS Merimbula and then cool off with a dip in the clear, shallow waters of this secret sanctuary.  www.visitnsw.com
Memory Cove, SA
This visually spectacular swimming hole is one of the jewels of South Australia’s coastline with the fragile eco-system that surrounds it hugely prized and protected. Only 15 cars are allowed onto the beach every day (you need to obtain a gate key) but it’s worth it if you can make the cut with stunningly scenic walking trails and excellent fishing spots providing things to do in between dips in the pristine waters. With the heavily vegetated headlands above the beach providing excellent shelter, Memory Cove is also an excellent camping spot and a night out under the stars in a bush paradise is something you won’t forget quickly. www.southaustralia.com
Cylinder Beach, Qld
Located on the northeastern tip of North Stradbroke Island, Cylinder Beach is a perfect spot for a family to pitch up in a 4WD (make sure you get a permit) and have a holiday. There’s a waterside camping ground for the tent-tolerant and family friendly resorts nearby for the non-campers. There are picnic facilities right next to the beach and the 500-metre expanse of white sand is perfect for beach cricket and lazing in the sun. Swimming is mandatory of course and this patrolled beach is great for water-lovers of all ages. If the conditions are right then it’s also a great spot for surfers of all expertise. www.queensland.com
Secret Beach, Mallacoota, Vic
Surrounded by Croajingolong National Park, the coastal village of Mallacoota in Victoria’s eastern Gippsland is a paradise of eucalyptus forests, stunning views and picturesque sandy beaches. It’s becoming an increasingly popular seaside destination but still retains the charm of being relatively little-known. There are three main beaches in the area south of the Mallacoota inlet and all are still fairly undiscovered. Secret Beach is the jewel in the crown, accessible only by staircase and home to a sand swimming beach, rock pools and for the more intrepid members of the family, a natural sea cave accessible at low tide. www.visitvictoria.com
