To decide you need to ask yrself four basic questions:
-where from the Med are we talking about, Med is 2.000 nm wide.. and in winter months is more dangereous than any Ocean.
-what kind of risk you want to take
-what part of the
Australia are you planning to go , west or east ?
-what kind of crew do you have ?
If you want to do it style and are not in hurry, I would go through the
Panama channel, waiting for the appropriate seasons for each
passage. If you want to hit east
Australia that's even better.
If you want to take some risk and are not far west of the Med, you could try yr chance through the gulf af Aden (I wouldn't, but I have a friend who does it to
Philippines every year..) This is by the way the shortest
route, particularly for the west Australia.
The last option is the cape Horn. From thereon, the conditions probably will be on the limit of
Belize, you need a very strong team..
In any case the last two options are not the routes that you would like to do with yr wife and friends..
If none of the options are for you, plan to send yr boat by a ship. I see lot of boats being carried by ship from
Malaysia and
Philippines to Marmaris and the
price could be worth checking from Marmaris back to those destinations.
