For those worried and wingeing about the cold...You'll be fine with a good sleeping bag and a swag....thats it!
These are from a few years ago at Lake Eucumbene...-10 to -12 deg C
This is me in a cheap sleeping bag with a woolen blanket over it in a swag

Both worm as toast and still catching fish!
Important thing is to make sure you get into the bag properly, zip up properly and you won't have an issue....
Bring it on!
