There are 0.00002 tonnes of methane in a cubic foot
0.00002 * 1,000,000,000,000 = 20,000,000
So 1 tcf of gas is 20 megatonnes of LNG, and 34 tcf is 680 megatonnes of LNG.

A tcf of gas is a LOT of gas. Exxon recently offered $US30 billion for XTO, a shale gas producer in the US with 45 tcf of gas resources (not all yet proven as reserves), which works out at around $US670 million per tcf. Coal seam gas is usually easier and cheaper to produce than shale gas.

CTP's first problem will be to prove up the projected resources, or even a significant portion thereof. Its second problem will be to monetise the gas in some way. LNG is an obvious option but at the moment it seems it's a buyer's market, and there are too many proposed and existing LNG projects in Australia. The simplest solution might be to pipe it to Darwin and sell it to the existing ConocoPhillips LNG project there (incidentally, the gas field in the Timor Sea on which that project is based has only 3.4 tcf of reserves). Another option is to convert it to diesel and aviation fuel via GTL, but that would be only marginally profitable with the oil price around $70/barrel. Both LNG and GTL would require a lot of capital to get off the ground, probably from a JV partner.
