There is so many factors that make the costs for a 20ft container that to try and compare on here is daft such as uk location aus destination these can make price differences of £300-£400 and $500-$600 over there, most good companies will be in the same area on price as all have costs to pack ship and deliver which are very close to each other. Please remember that to put together a good overseas move has lots of costs so to cut corners on price only reflects in service. I mean you wouldn't get on a 747 to fly to aus if it only had three engines but was 5% cheaper!
