According to @TeenChoiceGirl:
The awards air in the US Sunday, July 22 8pm-10pm ET live/PT tape-delayed on FOX & according to FOXTEL the awards will be screened here in Australia on Channel Eleven Saturday 28 July. There are a few times listed at the link but we’ll confirm exact times closer to the date for those who want to tune in. And of course on the day (which will be Monday 23 July in Oz) we will bring you all things Rob as they come in. Rob at the TCA’s always brings us so much gorgeousness but poor Rob, he really must be so over these types of events by now.
