NSW Drink Driving & Traffic Offences

hi all im a 29 year old bricklayer. i got done drink driving last saturday night. (0.188bhl) i losted my licence 3year and 8 mths ago for drink driving (0.137bhl) i lost it for 3 years and had to go on probationary for 12 mths which was meant to expire on the 20/6/12. i live in south australia, my question is should i get a lawyer and try to get my licence back or will it be a waste of time and money. i really need my licence for work. any help work be great thanks........buzz
