Thanks for all the replies guys, its really helpful. I think you're right Heath, its probably a word of mouth thing, just talking to the right people and waiting for something to open up.
Hey Rodomo, I'm in Coburg
I'm not too concerned about wether engine building will still be a career in 20+ years etc. For one I've got other qualifications I can fall back on but also, I really can't see Australian's giving up their classic cars anytime soon.
I've done one or two free Horsepower Academy courses online before, maybe I should fork out and pay for some more. Have you done many Heath and how did you find them?
Over covid I have built my first engine and really enjoyed it. Just a 186 on a shoestring budget. Have run in the cam (what a relief that was) and drove it a little, just waiting for travel restrictions to ease so I can go further than 15km to run in the engine. I really liked the engineering and science behind how to get the horsepower. Before motortrend got cancelled here in AUS I readily followed engine masters and learnt lots from that. I read ld Johnno's guide to death (that think is an absolute gift, thank you Old Johnno) and also read David Vizard's how to flow and port cylinder heads. Off the back of that I was able to pretty successfully port a 161 high comp for my engine (with help from HSD too) and really enjoyed doing that too.
If anyone's up for a chat on what its like being an engine builder I'm keen to hear 
While doing a bit more reading yesterday I was looking at Speed Works' webpage, a friend had his engine done there. Anyway, in the about section introducing the team theres Tony sitting in a boat with a big supercharged V8. It got me thinking about all the career photos I see of people with strained smiles, looking at a camera, standing up against a white office wall... I know which photo I'd rather be in
