The Mordialloc Boat Ramp provides small craft access to Port Phillip Bay (often affectionately known by the acronym PPB). The railway bridge provides clearance only for smaller boats.
There is council parking adjacent to the boat ramp, with trailer sized parking spaces for their exclusive use. The boat ramp is now free to use, as is the parking area for boat trailers.
The ramp and parking can be accessed through Governor Road.
There are public toilets and a boat washdown area provided.
While I have not personally used the boat ramp I have seen a lot of people doing so as I do pier fishing there frequently.
It’s extremely popular. Though a lot smaller than some other ramps.
The biggest issue relates to parking. Parking spots are limited and it can be very tight when busy. My inspection was on a quiet day, on a weekday in July. There were around four trailers parked. Parking wouldn’t have been a problem. Summer – peak boating season – would clearly have been more difficult.
Patterson Lakes boat ramp (about ten minutes drive further south) is a lot larger and possibly more suitable to some bigger boats.
Kayaking From Mordialloc Boat Ramp
By far the best access for people launching Kayaks would be Mordialloc boat ramp, located upstream on the Mordialloc Creek.
Access there is going to be easier than the beach.
Access near the river mouth is pretty limited for launching – if not impossible.
This is due to barriers and fencing place to limit vehicle access to the pier and beach. As well as the sides of the estuary being quite high, relative to the water level.
Fishing conditions are generally good in calm weather. Keep in mind the forecasts for weather and swell. During a big blow, it can get very dangerous.
In addition, powerboats and jet skis make heavy use of the estuary. This can be hazardous without due care.
Just offshore from the beach, facing south and to the west of the jetty, there are some good seagrass flats that do produce flathead and whiting. Pinkies 
The name "Pinky Snapper" refers to the immature Snapper. Their skin colour is different from adults (its pinker.)
Adulthood is usually considered on fish greater than 40cm - or in the 1.5 to 2kg - range, with a darker red colouration. should also be possible. Further offshore larger snapper is to be found.
