I'm not sure if this bill has been passed yet but it may be worth looking into
Section 104J Making a section 104J election
(1) This allows a person to elect to not be disqualified and instead opt for a
period of good behaviour for 12 months which will commence on the day on
which the disqualification was due to commence. The specifics of how this
will operate is detailed later in this document. A person can only make this
election if they hold a WA driver's licence. The period of commencement of
the good behaviour period may vary depending on any existing
disqualifications that may have to be served first. This is because demerit
point disqualifications are cumulative on any existing disqualification.
(2) A person cannot elect a period of good behaviour if they hold a provisional
driver's licence.
(3) When electing the period of good behaviour the person agrees that they will
not commit an offence for which 2 or more points can be recorded or a total of
two or more points can be recorded. And that they will not commit an offence
that carries a mandatory period of disqualification. In other words they agree
to not accrue more than 1 point over the 12 month period or commit an
offence that leads to a driving disqualification.
(4) The person makes this election in writing to the Director General in a form
approved by the Director General within 21 days after the Director General
served on the person the excessive demerit points notice.
(5) The period of the election for good behaviour applies for 1 year after it
commences or if the person breaches the good behaviour period by incurring
a total of 2 or more demerit points it applies until the person is served with a
notice advising them of the breach of the good behaviour period. In other
words it lasts for 12 months or until they are advised that they have
contravened the conditions of the good behaviour period, whichever is the
lesser period.

also
104H Expiry of demerit points
Provides demerit points will expire 3 years after the day on which the offence was
committed.
104I Excessive demerit points notice
(1) When the number of points recorded against a person in the demerit points
register reaches 12 or more, the Director General is to given the person an
excessive demerit points notice (in accordance with section 104Q - which will
be explained later in this document). The notice must state the following:
(a) the day on which that current number of demerit points was reached,
(b) the number of demerit points reached on that day,
© the period of disqualification (fixed by subsection (2)),
(d) the day on which the period of disqualification will commence (if the
person does not make or cannot make an election to serve period of
good behaviour in place of a disqualification - such election being
made under section 104J).
Therefore, if you are caught speeding... the day from which they back date the demerit points to is that of the day of the offence. If this means you have 12 demerit points awarded against you, you will then receive a letter stating that your license will be suspended from the date they provide.
If you wait until you get points back before you pay for the fine. Once you have paid that fine those points are backdated and technically you did lose all 12 points at one stage. The fact that you have received points back does not count because they were not received back before or on the day of the offence. So you will still have your license suspended for 3 months from a date decided by the Director General and stated in the 'excessive demerit points notice.'
