Insulin Pumps

Hey I have had type 1 for about a year now and was considering getting an insulin pump. I was wanting to use a closed loop or semi closed loop system ( I have only heard of minimed 640g system that do this and are available in Australia). I like the suspend before low system in the minimed 640g but I am a bit worried about the inaccuracies of the enlite sensors. I am currently using the libre freestyle which has always been accurate for me. I also like the omipod insulin pumps which don't have any tubing but I am pretty sure this is not available in Australia. If anyone could give some advice about pumps and the cgms that are avaiable in Australia that would be great. Thanks!
