If you live off Stirling Highway then the Claremont Jetty is a great option for your boat party.
The Claremont Jetty is secluded and sheltered but very convenient for locals who don’t want a departure from Fremantle or the city. It is the closest jetty to Mosman’s Jetty which is across the Bay and on the West side of the Swan River.
Parking is extremely limited so “drop offs” and “pick ups” are well advised should you use the Claremont Jetty for your boat charters. Also, be conscious of the walk: you will have quite a hike to carry food and drinks to the boat. Since the jetty is fairly long, bring a trolley if you can or if you are short of muscle 
DIRECTIONS TO THE CLAREMONT JETTY
If you are journeying south from Perth city, take a left on Bay View Terrace in Claremont. Follow the road down past the bowling club (on your left). Four blocks later you will reach the T-junction of Victoria Avenue. Take a left and then an immediate right onto Jetty Road. The water is in front of you. Oh…and the jetty is long for those carrying heavy food and drinks. Parking is extremely limited.
