The first speeches (known as "maiden speeches" in less politically correct days) for the 21* new federal MPs are now up on the web, and well worth a glance. While Garrett, Robb and Turnbull have attracted most of the media attention, my favourites are Tony Burke (ALP) and Andrew Laming (LP).
* Actually, there are 22 newly elected MPs, but one had already been in federal parliament, so there are only 21 first speeches.
