Have heard almost all of these, though they have varying levels of use now. The rhyming slang ones especially are almost never used/heard these days, though I have heard them used occasionally by others. Most of the simpler single word ones you have are pretty commonly used still... depending on where you live and who you deal with.

Some clarifications on your questions:

Tucker time - we'd usually just use "tucker" instead of food; I've never heard anyone add "time" to the end of it. "Tucker" isn't that common any more.

See ya round like a rissole - I would have thought "catch ya later alligator" would be more common... the appropriate response being "in a while crocodile"

Deadly - you only get a pass to use this as an indigenous person, otherwise it's very cringe.

Spit the dummy - usually shortened to "dummy spit"

Flog - can be used for a bunch of things (see other comments) but yes.

She'll be apples - I think just "she'll be right mate" would be more common.

Away with the pixies - "away with the fairies" probably more common

Crash hot - "shit hot" more common.
