UPDATE: Play will resume at 9:50 pm AEST after a lightning delay in the Wallabies-British & Irish Lions Test.
The third Test between the Wallabies and British & Irish Lions has been halted for lightning.
Players left the field as the conditions turned for the worst just after the break, with the two teams returning after a 30 minute delay.

The rain set in well before kickoff as Sydney dealt with an onslaught of bad weather throughout the weekend.
It occurred in the 42nd minute after James Ryan was knocked out after an awkward tackle on Will Skelton.
Ryan was carted off the field as the players followed, with play required to stop for at least 30 minutes until it clears.
The lightning has caused havoc, with four games across NSW in several codes delayed as a result of the multiple strikes.
"When the lightning strike is within 6 miles of the venue, it is recommended that players are removed from the pitch," World Rugby's policy on lightning says.
"Recommendations on best practice also state that it should only be considered safe to return to the field of play a minimum of 30 minutes after the final flash of lightning or clap of thunder has been seen/heard."
The Wallabies were leading 8-0 after a early Dylan Pietsch try gave them the lead.
It continues the bizarre trend of games being affected by the weather, with the Wallaroos suffering a similar delay last week in their defeat in Brisbane.
The game had already seen multiple players fail HIA, including Wallabies flyhalf Tom Lynagh and Lions skipper Maro Itoje.
