I was competing with families with emotional buying...all offers were above list and many highest and best.

You will get some sense of the economics (price paid for lots and sold prices of competed projects). 

You'd be better off introducing yourself to the players at the auction, tell them what you're looking for, and then letting them wholesale it to you.

I’m an Australian, and I want to invest my 60k towards the end of this year after I feel more competent in my knowledge.But looking on Roofstock, Zillow, Redfin etc, I’m seeing what looks like nice places (physically) for roughly 100k.

One thing you definitely want to make sure of before you quit your current position is that you won't be asked to sign a non-compete agreement that would prevent you from doing this on your own or with another wholesaling company. 

People can surf channels on cable, or log in with their own account to whatever streaming service that subscribe to.I also leave some adult DVD's next to any Blu-ray player.

How can I compete against this?

The big players have a large enough portfolio to accommodate, albeit begrudgingly, the changes in RSO rules.

Usually it's best to invest in your backyard, out of State is always a challenge, because you are competing with the locals.
