Would you please provide a link to the specific section of the 'The Australia Consumer Law' that you refer to.
If you are dealing with Aldi etc. you can just take the faulty thing back and they
will refund the purchase price (only within a month or so, unless covered by a manufacturers warranty?).
The right to return faulty goods, within a reasonable time, is a
separate matter. But long after any right to return the goods would have
expired, the company has to make spare parts available, so that the
consumer is not faced with discarding goods just because they have
developed a fault.

Unfortunately, Austlii has problems with schedules, and cannot provide
links to individual sections.

58 Guarantee as to repairs and spare parts
(1) If:
(a) a person supplies, in trade or commerce, goods to a
consumer; and
(b) the supply does not occur by way of sale by auction;
there is a guarantee that the manufacturer of the goods will take
reasonable action to ensure that facilities for the repair of the goods,
and parts for the goods, are reasonably available for a reasonable
period after the goods are supplied.

Now, there is a possible ambiguity as to what "reasonably available"
means, but I think a court would find that a spare part that was
unreasonably priced, by reference to the cost to the company of making
it available, then the part would not be "reasonable available".
