Taking the dog to the beach on a hot summer's day is a great way to relax. But not all beaches are dog friendly. So if you're looking to take your dog to the coast this summer, here's a few of the country's most dog-friendly beaches.
Sunshine Beach
Where: Noosa, Queensland
Only a 10-minute drive from Noosa, Sunshine Beach also welcomes dogs with open paws. Once known as Golden Beach, its long white beaches make it a paradise for anyone who loves fishing, boating, surfing or just relaxing on the beach with family and friends.
Restrictions (限定): Dogs can freely explore the shoreline from Noosa National Park to the path leading from Seaview Terrace.
Tallow Beach
Where: Byron Bay, New South Wales
With white sand that stretches (延伸) for miles, and clean, clear waters washing its shores, Byron certainly doesn't want for beautiful beaches — and Tallow Beach is no exception. This seven-kilometer-long beach stretches all the way to Broken Head Reserve.
Restrictions: The beach's dog-friendly area starts near Jarman Street and stretches north to the outside of Arakwal National Park.
Muirs Beach
Where: Coles Bay, Tasmania
One of the few beaches that falls outside of Freycinet National Park, Muirs, is a great family beach that welcomes dogs, too. Compared to famous sheltered beaches of Freycinet, it is more open to the waves from the Tasman Sea, making it ideal for windsurfing. The beach itself is very long, so there is plenty of space to let your dog run free.
Restrictions: Dog owners must respect the environment and use the poop bags provided at the entrance to the beach to get rid of any dog waste.Fines apply (运用).
Yorkeys Knob Beach
Where: Queensland
Located just 15 minutes from Cairns, Yorkeys Knob Beach is a great spot to relax with your dog. Named after a local fisherman called "Yorkey" who lived on the rocky hill (“knob”), this wonderful little beach is one of the best-kept secrets in Tropical North Queensland. It is ideal for swimming and snorkelling in the summer season.
Restrictions: The southern end of the beach is the "dog off-chain" end where your dog is allowed to run free; dogs must be on a chain in all other areas of the beach.

A．Tallow Beach is not popular in Byron Bay.

C．they’ll get punished by paying money
