My one and only experince of the Police in NSW so far (moved from UK 8 months ago) has not been positive but no different to in the UK.
Got pulled over by an unmarked police car last Friday for 'using my mobile'.
When he asked me if I was using my mobile I said 'yes', because I was - I was using a bluetooth headset and had the phone in it's cradle.
unfortunately, what he saw when he passed me was my hand up to my ear to press the little button on the headset to make it connect to the phone -
Hand + Ear + Shadow + Tinted windows = looks like I had a phone to my ear.
It took a bit of argueing to convince him that in between him seing me, him turning quickly and following for 500m I had not in fact had time to put the phone into it's cradle and dig out my bluetooth headset and stick it on my ear and that I was using it rather than the phone directly.
He let me off, but only in that way that Policemen have - in a 'Look I'm completely right, you, sonny-boy, are in the wrong, I will not admit that I am wrong (but obviously can't prove it)" - kind of way. Cos lets face it if he was confident, he'd have charged/fined me.
I don't have anything against him for stopping me - i've no doubt it looked like i might have had a phone to my ear but the attitude just gets to me a bit - "I observed you with your phone to your ear and I have a video camera in the car and have recorded EVERYTHING for the past 2 minutes" - as if I did anything wrong and this damning evidence of me driving at 45kph doing nothing wrong was going to crush me?!?
Besides - I clocked the car as soon as I saw it coming towards me - why do they think they're incospicuous in a bright white Falcon with blue stripes, bonnet bulge and a Boss supercharger (sorry, not quite integrated enough to Aussie car culture to recognise all the different variants of fast Falcons) . If I had been illegally using the phone there was no f-ing way I would have tried to swap the phone into it's cradle and put an earpiece in with him right behind me!
Anyway - I'm sure that they do a fine job most of the time - I just wish that they were out on the M4 stopping cars from overtaking oni the inside lanes (a pet hate of mine

) or out catching the theiving junkie scumbags that broke into my car last november and nicked a work laptop and $300 leather bag!
The odd thing was that afterwards I spent the whole trip home thinking about it as I was so wound up - which in itself distracted me from driving more than a phone call ever would. I had to pull over for a couple of minutes to calm down cos I was so p-eed off at the guys attitude.
Moan over.
PS after 6 months of customs shenanigans, apathy and lack of progress, my UK mini is almost ready to be registered - thanks to Chris at OzCooper (and Steve at Brickworx for some new doors (if they've been sent yet)) - I am so excited, it's been 9 months since I've driven a mini........
