I think you mean around 2 hrs, from memory Town Hall to Woy Woy stations is 1.5 hrs on peak hr trains, then you have walking/ car/bus trip time at either end. About 1 hr gets you to Berowra or St Marys or Liverpool in train travel, then you add travel time at either end. Still in traffic there are folks doing nearly an hour on the bus from the Eastern Suburbs...In New York, people are paying like USD $2M or more to live 1 hour away from Manhattan.
In London, people are paying GBP 3M+ to live one hour away from the city centre.
In Sydney, commuting just over one hour by train takes you to Woy Woy, where you can buy a 3-bedroom freestanding house for the equivalent of USD $400K.
