Wow. The short answer is, don't believe everything you read.
The plans on the Optus site are - it seems - entirely wrong. Well, not entirely, but partially. The data allowances with the Yes Cap 49 and Yes Cap 59 are actually - I asked him three times to confirm it - 500Mb and 700Mb respectively. Beyond that, the charge is 35c/Mb (or you can purchase a 200Mb block for $19.95).
Moving *upward* between plans is allowed, but it's a ratchet system: as soon as you move up, you can't move back down until the end of the contract period.
As for phone locking, the phone is locked *within Australia only* for the duration of the contract. So you can immediately use it on other network's SIMs overseas, but you can't put an Australian Telstra or Vodafone SIM in it until you've seen out the contract period.
