I was 4 years with the NSW Department of Agriculture attached to the Australian Quarantine Inspection Service (a long time ago now so things may have changed) - and all of those things were of interest but mainly the issue with wood and bamboo products is borers or the risk that it is green and propagatable.... being a gigantic island we have a lot less of these pests and weed than most places. But no - as I recall shoes were not usually of interest except for the dirt on them.

http://www.daff.gov.au/aqis has a cover story about a recent rock festival where borers were found in band instruments..... and links to the ICON database where you can look up things like regulations on the import of bamboo products into Australia.

Inspection doesnt find everything - I have a late Edo / early Meiji period Japanese storage chest that I had to build a quick and dirty fumigation tent for in the yard and fumigate after I found borers trying to migrate from it into my house....
