Difference between tariff and fare base amount

[bjg-]

Hi,
I have been looking at some Qantas domestic tariffs but I am confused how they tariff amount is more than the base amount, it doesn't look like the tariff is higher because it includes only GST?

I am sure this is a very "newbie" question, but I am genuinely perplexed, can anyone explain how this works (example below) ... <edit>

Many thanks in advance.
