How do i move back to Australia? :(

Hi everyone ,im basically an aussie in exile. how it all started was i met my now wife online,after which we got married when she came on a trip to australia. so i did the easiest thing and got a 2 year yms visa to the UK but we so badly want to return home. the problem being i dont have a job in Australia (but i have one here just a factory job) due to being here in the UK and wont be able to meet the finacial requirements to bring my wife and two kids back with me :( what options do i have and how hard will it be .i feel trapped here. thanks in advance for any help.
