Bike Reg is 696.30 and car is 830.40 including insurance.
As you live in Victoria, part of that $696.30 will be the sneaky "road safety tax" which is currently $73.70.
Notice how they don't tell you that on your rego renewal notice, they just lump it in with your TAC... 
Actually, that reminds me...When this road safety tax was first introduced, you had to pay it on every motorcycle you owned.
Due to intense lobbying etc this was eventually changed to just the one charge, regardless as to how many motorcycles you have registered.
A bit of a "win" but, we're still lumbered with a "tax" that no other road user group pays... 
Just a bit of a heads up for any member in Victoria that may have more than one registered motorcycle...
You SHOULD only be paying the "road safety tax" on
one motorcycle...
BUT, don't assume Vicroads will automatically only apply it to just the one motorcycle.
You'll need to visit Vicroads and apply for an "exemption" on any other registered motorcycles in your name.
Definitely worth your while @$73.70 a motorcycle...
