How do you manage the logistics for traveling on 8hrs to Sydney when you are pumping exclusively (perhaps need to pump at least once) and baby takes only ebm? Is beast milk allowed on hand carry at Australian custom?

Ahhhh... Im not too sure. However, i never had an issue with expressing. I get very frustrated with the electronic pumps. At times i hand express till i got the hakka pump. So not sure how your flow is like with the medela. You can also try to massage your breast every now and then for better flow.
