Penalty Units

Hello All,

I have been a long time lurker on this forum and for the information so freely given by many of you, I am truly thankfull.

Through out the Strat Schemes Management Act, there is mention of 5 penalty units even as high as 100 penalty units for breaches of the act, however I have not been able to find what a penalty unit is, can some one explain penalty unit?

Thank you.

David
