Why did these poor Vietnamese choose to try and enter the UK?

It is absolutely horrific how these poor Vietnamese died in the back of that lorry trailer in Essex but why were they there? It seems some may have had relatives in the UK but if you look at a world globe you will see a large country called Australia due South of Vietnam and much closer to Vietnam than Essex. Oz also has a large Vietnamese population in Sydney and Melbourne where these unfortunate people might well have had relatives so why choose a longer more difficult journey to Essex?

The answer must be that Australian immigration has a well deserved reputation for rigorous application of its strict but just immigration rules that prioritize Australia’s needs .or as Donald might say Australia first. The UK is still seen as a  soft  touch a view encouraged by the bien pensants of the BBC. That is a large part of the reason they try to get into the UK and it will continue until the BBC changes its liberal elite stupidity they broadcast to the whole world. They bear a large responsibility  for encouraging would be migrants undertaking these dangerous journeys.The  BBC which is like Mary Poppins practically perfect in every way will never admit their failings.
