Gaazunda unfortunately you are not yet ready for the Torres Straits. Most operators there are Cairns Based and their normal minimums are 2,000 hrs total and 500 hrs multi ( and so is their recruitment Cairns Based).
Flying in the Straits represents some of Australia's most demanding flying and it is not the place to find out whaT YOU DON'T KNOW OR CANT DO.
Special category aerodromes, two of them under 500 metres and one just over, slope, visual effects on approach, crosswinds, terrain affected winds etc all combine to require the highest standards of accurate flying.
Weather in the straits presnts it's own challenges at times and this too requires a solid background.
Then there are also the CAO 82 requirements etc.
Don't give up, go and get your time up in Kunnunurra or Karumba or Jabiru or Maree or parachute dropping and when you have the necessary experience then try for it and be rewarded with some of the best flying in your GA career before you make it to airlines.
There is one charter operator up there who does not pay anywhere near the award ( read fly for free?) yet you would be in a very expensive ( food and accomm) part of Australia.
As an underline to the above, there was an unfortunate weather and experienced related fatality there just over a year ago. Some one was silly enough to permit a 350 hr pilot to fly in the straits during the Wet Season.
Or is your question just a windup?
