I cant see where it lists the freeway as being banned for cyclists?
Here (from the link above):

- Deer Park Bypass
(My emphasis in there)
They don't explain what the Deer Park Bypass is so I went to Wiki for the explanation of where it starts and ends. It is the part of the Western Freeway after Ballarat Road that connects the Freeway with the Ring Road. So to me that is anything after Ballarat Road towards the city.
EDIT: Hmm, finding the correct page on the VicRoads website (as BNV has the wrong web link) makes it more confusing though:http://www.vicroads.vic.gov.au/Home/Mor ... ToRide.htm
Cycling is not allowed on urban freeways. However, cycling is allowed on the shoulders of some parts of rural freeways.
Rural freeways include the Western Freeway, the Calder Freeway, the Hume Freeway and parts of the Princes Freeway to Traralgon.
Urban freeways include the Western Ring Road, the Northern Ring Road, the Eastern Freeway, the Tullamarine Freeway, the Monash Freeway, the West Gate Freeway, the Mornington Peninsula Freeway, the Princes Freeway to Werribee, East Link and City Link.
Bike riders are also not permitted to ride on the urban sections of the Princes Freeway and the Calder Freeway.
Cycling is permitted on the shoulders of rural freeways because:
these areas provide the most practical route for bike riders
these areas have relatively low volumes of traffic on main roads and entry and exit ramps that bike riders need to cross.
Cycling is not permitted on urban freeways because:
there are other safer routes that bike riders can take
these areas carry relatively high volumes of traffic, including entry and exit ramps. There are many more ramps on urban freeways and these ramps often have more than one lane.

It doesn't mention the Deer Park Bypass.
So you might be able to get away with it if you go by VicRoads' website. Maybe print out a copy of that VicRoads page and carry it with you as you ride along the freeway to Robinsons Road just in case someone decides to pull you up on it? I'd be tempted to do that.
