Welcome to AFF, NarelleB! Hopefully your travels are smooth and you find the forum valuable.
If you want to distinguish the different ways to pay for your booking, I've outlined them below for future reference.
1) The most common is paying the full fare with money, a
"cash fare" or "revenue booking". In the image below, pick your choice from the first three options (sale / saver / flex).
2) A
reward booking. This is what RichardMEL referred to as those which QF occasionally releases for booking at a reasonable amount of points. In the image below, it'd be 31,500 QF points plus AUD $122 for taxes & fees.

3) Another way is to
use points instead of money to pay for any ticket. In this case, you'd take the sale / saver / flex fare and decide to pay for them in full using points. As you can see, that's a lot more points than a reward booking and most times poor value (in terms of what you get per point).
You may have heard of complaints in social media and some mainstream news that
"Qantas has jacked up the amount of points needed to astronomical levels. What used to be 200,000 point to London is now over a million points...". This comment confuses two things: rewards and choosing to pay using points. The same logic applies to any of the flights where a reward is available. QF just has made is much easier to see the full cost in points and this trips people over when they see the "a million points to London."

4) An added nuance is the
'points plus pay' option where you choose the split between the points and $. This is done by choosing a normal cash fare and when you advance to the payment page, you can choose to replace some of the money with points. This, again, is usually poor use of your points (you get low value from them) but the choice is there.
