Twenty-eight wickets have fallen across two games in two different states on one day in the Sheffield Shield, in a stark turnaround of Australian batting fortunes.

Key points: NSW was all out for 150 and South Australia was dismissed for 159 in their matches

Last week, eight batsmen in the running for Australian Test spots for August's Ashes put on a show.

Marcus Harris, Kurtis Patterson, Cameron Bancroft and Nic Maddinson all scored centuries, while Joe Burns, Marnus Labuschagne, Matthew Wade and Travis Head all reached 50 at least once.

In addition to those contenders, Tasmanian debutant Charles Wakim, young South Australian Jake Weatherald and former Test wicketkeeper Peter Nevill also reached three figures.

But after the batting onslaught of round seven, the start of round eight was a completely different beast.

With New South Wales facing Queensland and South Australia taking on Western Australia, there were plenty more runs on offer for Patterson, Bancroft, Burns, Labuschagne and Wade on day one, but no-one cashed in.

In fact, no batsman reached 50 across the first day of the two games.

The top score was a 144-ball 43 by unheralded South Australian opener Conor McInerney as the Redbacks were dismissed for just 159 inside 63 overs at the WACA.

Western Australia was then reduced to 4-75 in 24 overs before stumps, with Bancroft falling for 11 and Mitchell Marsh gone for 17.

Meanwhile, Queensland's Luke Feldman cashed in on a Gabba greentop, taking 5-20 from his 11 overs as the Bulls had New South Wales all out for 150 in 55 overs.

Afterwards, Test batsmen Burns (28), Labuschagne (0) and Matt Renshaw (3) failed as Queensland ended the day on 4-67.

The third Shield clash of the round between Victoria and Tasmania will start on Tuesday, with Harris, Wade, Maddinson, Tim Paine and Will Pucovski the major batting names to look out for.
