Boland's double-strike the highlight as rain ruins day one in Gqeberha

Key points

• Rain has almost entirely washed out the first day of Australia's second Test against South Africa in Gqeberha. Scott Boland struck twice in two balls during a brief spell of play, leaving South Africa at 2-20 after 12.2 overs.
• Boland was included ahead of spinner Nathan Lyon, giving Australia four seamers on a green pitch. Play stopped again after only a handful of overs following rain.
• Marques Arkerman will resume on 5 not out alongside captain Temba Bavuma on 4 not out on day two.
