WTF enough is enough!!!!!!!

[010 f6 ute]

i got pulled over by highway patrol today, my f6 in registered in qld but i have a NT licence because i work there for most of the year. Now i have asked the Qld department of transport and said its no problem and i get one cop that says fine no worries i can understand that than the next time i get pulled up i get told my licence is no good i cant drive in this state when i tell them that main roads said its fine they tend to lay off and forget about it till today when i got threatened to be done unlicensed when i told her ive seen main roads she said doesn't matter they have nothing to do with your license its not up to them all the blokes i work with never get hassled about it but they are also alot older than me being 19 im the youngest there do u think this is a age thing? if i get done unlicensed i will lose my job i spend most my time there so i have to have a nt licence or i will lose my job anyway i told her i need it unless i quit my job all i got from her is thats some thing you got to think about is there anyway to give it back to them and prove im in the right? and for the record i was not a smart ***, i didn't back chat and didn't raise my voice ohh and all the tickets i have been given are from women cops
