I have never worked for this company but I do know the Ops Manager very well, and you would not find a more professional guy anwhere. He has been in the industry quite a while, and I know that he would not be working for anyone who could be discribed as "shonky" Those that know him can vouch for that.
I spent a day with him a few months ago while on holiday in Oz, to look at their operation, with a view to perhaps working for them in the future. Everyone was very friendly and it seemed like a very well set up, and professional company. If you have a concern, simply vist them. There is always someone who is not happy about something.
