In Australia, if you are just starting out, it's pretty hard to go past the new Merida E160 400 at AUD$4994.
Reasons being it has the top of the line EP801 Shimano Motor, and the 630Wh Shimano battery so you won't have any battery issues, that come from running the Shimano compatible batteries. And with that motor, you will not need to upgrade that motor for the foreseeable future, no matter how advanced in the riding you become.
The Transmission is basic for a EMTB, but if you really get into riding, you can easily and cheaply upgrade to the Electronic 11 speed Linkglide transmission, which will give you Autoshift and Freeshift.
The Fork is capable but heavy, so is another point of upgrade if you really enjoy the riding.
The rear shock is probably good enough to see you through to some pretty advanced riding. But once again, if you are really pushing the bike in the future. You can upgrade it.
I believe this is the best bang for buck in an Enduro capable EMTB in Australia, if you are just starting out. If you end up just sticking to Trail riding. You won't need to upgrade anything. But if you really love the sport and want to try more technical terrain. The bike will be capable, but best to upgrade those 3 items I talked about.
Best of luck with it.
