Biddle had a history of previous drink driving offences dating back to 2002, 2004 and 2010.
"Make no mistake, you have come within a hair's breadth of prison," Judge Denys Barry said.
"If you come back on another drink driving charge, you will be turning a key into a prison cell."
Judge Barry said he did not believe Biddle understood the seriousness of the situation after she "blindly" pleaded guilty and did not request any legal representation. He deferred the case temporarily and recommended the defendant seek legal advice.
Judge Barry took the early guilty pleas and Biddle's positive work ethic in the shearing industry into consideration.
Biddle was disqualified for two years for the June 29 offence and disqualified indefinitely for the November 10 offence. She was sentenced to a four-month community detention period with a home curfew between the hours of 4.30am and 7pm, and 150 hours of community work.
