If you are thinking about underdeclaring your packages in the next few months just be aware Customs will be more stringent.

"The operation, which started at the beginning of 2011, involves Customs officers performing an increased number of examinations of international mail. In addition, the declarations of air and sea cargo will be more stringently checked. With the increasing popularity of online shopping and eBay purchases from outside Australia, it is a common practice for expensive internationally shipped items from some regions to be marked as gifts, samples, or declared with a low value to avoid the $1000 GST threshold that applies in Australia. Packages that exceed this threshold require an additional 10 per cent goods and services duty payment on the value of the items, as well as Customs processing fees, before being released to the purchaser."
but what about the seller who makes the price undervalued
i.e.
i purchased some items that were worth, say $1500, from overseas, what happens if the seller deliberately puts $800, because i know sellers do this
