True Protein are running their free sample offer again, which proved fairly popular last time around: https://www.ozbargain.com.au/node/149444.
Four different flavours of their NZ sourced whey protein concentrate are available: French Vanilla, Rich Chocolate, Iced Chai and Strawberries & Cream. First sample is free including delivery, additional samples are $2 each.
Site says Facebook like is required, however I managed to checkout without liking their page. Per rep comments below, Facebook like required.
I ordered 2kg of WPI during their recent BOGOF offer and was happy with the purchase.
I didn't complete the transaction, however it looks like you may be able to add a sample to an order less than <$150 and still get free shipping on the total order.

Hey Guys, sorry I'm a bit late to the party.
We are offering free samples again AND we do check to see if you have liked our facebook page PLUS we are actively checking to see if there have been multiple orders to the same address and reserve the right to not send the sample in this case.
Unfortunately, we have received a massive number of free sample requests (from ozbargain) and very few corresponding facebook likes. We have to review every order and ensure that the like was made.
If you have no intention of adding a like, or if you have already had a free sample, please save us the extra work of having to check your order. We appreciate the "It doesn't hurt to try" mentality, but in this case, it does hurt us. We still need to review every order, and although we have a system in place - we are a small company and this costs us valuable time.
Should we continue to receive a huge number of ozbargainers trying for a free sample without performing the very reasonable conditions we've set out, we will simply have to remove free samples from our website altogether.
That would be a shame, because as is evident from many of these comments and the comments from those who received free samples in our last post - the product is awesome and we would love to give everyone an opportunity to try it out!
Thanks for your understanding and I look forward to hearing any questions or thoughts you may have here.
