It's always good to see other Aussies here. I'm in Oz too. I don't know if you've heard of it but we have a team Australia on steemit. If you join it could help to get a few more upvotes on your posts. You have to jump through a few hoops to join but the guys on discord should be able to put you on the right track.

The details are in this post under the usual community notices heading

Your form is really quite good compared to a lot of people I see doing deads these days. Just try to keep your head more neutral and don't tilt it back as much. It's not essential but it can give you a bit more power and can also help to prevent pain in your neck and traps.

I steer people towards this youtube vid these days, the guy who did the vid demonstrates it pretty well exactly the same as my Olympic coach taught me.
