And sentences can be cumulative (ie 10 yrs + 10 yrs).
One case where someone in 2010 was caught with the means to make fake money and about $32,000 in fake cash received a 4 yr 3 mth sentence in NSW.
Many cases involve other offences like drugs and firearms.
One guy had 51 fake $1 notes in 2016! Why?
The hard part is not making the money, it is spending it without being caught.
