If you can tell us a bit more about what kind of puppy you'd like - we might be able to point you in the right direction. If you don't mind gambling on a mixed breed... there's
If you want a working dog - there's "Australian working dog rescue" on facebook.
Beware of facebook rescue groups that try to make you go get the dog out of the pound so it doesn't get PTS. Puppies don't get PTS because they are always easy to find homes for.
Some rescues are better than others. Some pounds and shelters are better than others even ones under the same "umbrella" eg not all RSPCA shelters are the same, not all AWL shelters are the same.
The ACT pound system has a very good record for getting dogs that end there back in their original homes or rehomed without PTS. Not so good with cats and kittens - there's just way too many of them and so few are micro chipped. No pound / shelter is great with rehoming cats sadly.
But there is a system for getting nearly 100% of dogs in shelters and pounds in to foster care or rehomed... it involves taking dogs out to meet would be dog owners - away from the shelter environment - which is traumatic for the dog and the humans. I heard a radio story about it - some of the shelters in the USA are rehoming all suitable dogs ie the ones that are friendly.
