Ouch...
The penalties for speeding over 25km, 35km & 45km are prescribed as mandatory suspensions by legislation and the magistrate does not have discretion to change this to a probationary period.

However I would at least speak to a traffic lawyer as Ian suggested... good luck!
Edit: Found this
Can I stop my licence from being suspended?
Your licence can be saved if the magistrate believes you were driving less than 25 km/h over the speed limit, at a speed less than 130 km/h. Otherwise the magistrate has no choice and must suspend your licence.
If your licence is suspended, the minimum suspension period depends on how much over the speed limit you were driving:
25 to less than 35 km/h over the speed limit – one month
35 to less than 45 km/h over the speed limit – six months
45 km/h or more over the speed limit – 12 months
any speed of 130 km/h or more that is not covered above – one month.
Note: this suspension period is in addition to any suspension period due to demerit points.
