I think you could easily do some flying here and I would say why not go for it? Talk to a few schools around where you will be based in Oz.
You can get some fun experience and enhance your skills and it all counts if what you are interested in is enjoying yourself and becoming a better pilot.
NB whatever you do, you won't get any solo here unless you do an Oz medical though. You no longer need a student licence here - just need a medical.
With a medical you can be allowed to be sent solo. See

Depending how much training you have already done and what free time will be available you might easily get at least an RPL.
An Oz RPL (recreational pilot licence) doesn't carry any weight overseas but the skills and experience you gain certainly will not be wasted.
If you are reasonably advanced in your training (eg at navigation training point) an Oz PPL is also within range if you really wanted to go for it and willing to do some study.
