Maybe you can do landscaping? It involves some interaction but so does everything.

I am looking for a job that involves no interaction, cash in hand and flexible hours of working the hours I want to work. No more than 3 days per week, preferably 2 days per week, work life balance.

Many years ago, way back in my day, just after completing my accounting degree I considered doing CPA or CA but lots of money paid up front and it could not be put onto student debt. Masters degree would be out of pocket too so I decided not to pursue further studies.

So you were trolling us all this time :D

Then, like I said, try looking for work from home. Freelancer, Upwork or any such website may be helpful for you to find anything. You can decide the workload yourself, especially if you're just working by commission.

That's exactly what some beggars are doing. They "work" more days the week, though.

Needed 70%+ average and good work experience and be captain of sports team to show leadership to get into a Big 4 accounting firm, bank, commerce or government. I fell well short of those  high expectations and ended up becoming an unemployable dead beat posting online complaining about it.

"From my observations all the top 30% of students that are locals end up in the 'best' graduate roles such as big 4, commerce, banks, government, maybe some mid tier firms.

After that, all the boutique and suburban firms go for international students (cheap expendable labor that never says no).

In accounting if you don't get a good grad job in commerce, big 4, and maybe some mid-tiers you are pretty much doomed to be working in small 'boutique firms'."

With linkdin, cellphones and social media any decent job you try will check your background very fast and your fake resume will get you jail time.

One thing is to give some exaggeration on your experience (like something you done few times in work become something you are skilled, or a party you organized in the company become experience in planning events) another is to plainly lie.

Those social welfare money have to come from somewhere. Your tax make the car cost double.

We are talking 10 years since graduating college and I have not worked any job in 10+ years. It is a black hole nightmare situation I doubt anyone wants to be in. I might as well claim I have served a long prison sentence. I have no LinkedIn, no social media accounts besides VGCHartz if this counts as a social media account. I am basically a ghost.

It would make it even easier for potential employees to discover you are lying in your resume.

So Aussie have something like a work book where every formal employer sign when they hire and dismiss you? In Brazil we have and as soon as you present your work book a lie in employment would show up.

Also if you are looking for a 2 day work, best do non-formal work, or perhaps look for janitor/security/etc job in condominiums and the like (they need to hire people for weekend for the employees of the week to have rest). But self employment would be better for all your requirements, doubt you would make any money since you don't really want to work.
