Business on the side in Abu Dhabi

Hi everyone, can I firstly say how valuable this forum is. I've been actively looking to relocate from Australia to Abu Dhabi for a year now and just by reading other people's posts and comments I've had most of my questions answered.

I've just accepted an offer and after I sign the paperwork and post security clearances etc I should be moving out there with my wife and 2 young children in April/May.

Apart from my day job here in Australia, I have a side business as a video producer, which I do for fun but also make good pocket money from it. My question is, can I continue this video production business as a side job in the UAE or is it illegal? It's more of a hobby for me, but if someone wants a professional video, I charge them for it.

Thanks
