These courses are in the "permanent" free section (they don't have a price tag).
What is expiring in '6 hours' is just one of their "Courses starting at A$14.99 each (a savings of up to 90%)" promotions, but it really isn't 6 hours either, it's just a scarcity timer giving a sense of urgency to take up the sale prices.
The timer restarts itself when you clear cache and re-visit.
