LPG " Highway Robbery " by Petrol Cartel in Hervey Bay !!!

I regularly fill up my LPG tank in Brisbane on the way home to Hervey Bay. The price of LPG is 64.5 c ( on average ), having to refill in Hervey Bay ( dead end so no choice, and don't THEY know it !) all Petrol Stations charge 97.5 c ( if this is not price fixing ?!??! ), that's 33 c more then Brisbane ( or 1/3 more ) , if they did that same scam to petrol prices, there would be " blood " in the streets ... very sad, such blatant rip-off from regional people that can leased afford it ! Shame on you !!!
