Are you on a CTO (community treatment order)? If so, then your situation is pretty effed up and they can indeed come and drag you off to the hospital like in the movies (no kidding).
If you're not on a CTO and not acute, then there's no imminent threat and you can pretty much put your foot down and say you won't take it. I would however advise you to be a bit smarter about it though.
In no case should you take excessive doses! Okay
You may come close to passing the tests with somewhat realistic amounts showing in your blood but it's far too risky due to side effects and with clozapine you're gonna feel like shit and drool all over yourself. Plus if you stuff up and take too much you're gonna draw more attention to yourself, they'll want you back to do more test to make sure they're not overdosing you.
If you wanna go down this path, then take your regular dose in the 2-3 days leading to the blood test. Chances are the dosages will appear to be lower than what they should be but you won't have zero amounts showing up so you can always say you had the shits (hence the reduced absorption), or that you took your last dose many many hours ago (way too early e.g. you were tired and went to bed early) or that you forgot to take the last dose by accident. Be smarter... delay things, muck around and even if you are on a CTO they'll have to be very patient with you, always appear cooperative and nice. You can drag this on for a long time, you only have tests once a month. Forget to take the dose one time, have diarrhoea next, "go visit the relatives out of town on the day of the appointment", tell'em you have to go to a job interview (they can't deny you that), tell them you just got a new job and have to work hard to prove yourself and can't take time off to go to the appointment. If you drop out of the system slowly like this, they are lot less likely to take drastic measures to coerce you into taking the medication. Play their game. Never say you THINK you don't need to take medication, if you feel the urge to show them some attitude then tell them you object taking the drug because of the side effects i.e. risk is greater than benefit. If you tell them you don't think you need meds or are not explicit enough as to why you don't wanna take them, you'll earn instant "lack of insight" points and they'll bag you up.
Other stuff I'd do: tell them you moved and give them a fake address... but something that's realistic, like a friends place. So if they come knocking, you likely won't be there. They will likely come during business hours. If they come knocking you'll know, they're fucking loud and they'll probably come with police backup... they're assholes. LOL, remember your friends won't come to your front door with flashlights like a gang of thugs. Had that happen to me and I thought something horrible happened and they came to tell me someone died and I opened the door... big fucking mistake. Do not open the door (pretend you're not at home), have someone else open the door and say you're not there, you moved out etc.
BTW your profile states you're in qld... you only need to move across the border to nsw. If you're on a CTO that only applies in QLD.
Good luck mate... stay healthy. If drugs make you relapse, don't take them obviously
