Though admittedly I haven't gone through the deal (that was made public on the day of the signing) with a fine-tooth comb (who has the time to do that?), here are a few things about the deal.
China has an abysmal human rights record. They have a single party system, and voices of dissent are oppressed with Chinese efficiency. Unions are destroyed if they ever start to form, and there is widespread use of child labour. But what does opening up our trade barriers have to do with this? And we can talk to them better now that we've given them preferential trade, right? Besides, we're going to make a killing out of this deal. Local manufacturers will be hurt, but they are almost gone already anyway, and they'll be given time to "adjust" before tariffs are removed completely (ie. move their manufacturing to China). We are an exporting nation, so will benefit greatly. We should be proud that we were the first nation to stand beside the senior Chinese Party officials and put our flag up next to the Chinese one to signify a uniting of two nations under the auspices of trade.
Please vote in poll now, or before it closes if you need time to think and read about it.
PS It's a bit of a fallacy to call it a "free" trade deal. No free trade deal is truly free - otherwise it would be a very simple document. An almost free trade deal is what it really is, with a few mentions of immigration and stuff.
