Most of Australia's players will be in line for a bonus of at least $60,000 if they can avoid defeat in the inaugural day-night Test, thanks to a spike in prizemoney from Cricket Australia. 
The reluctance of players to use the pink ball in Tests dissipated after CA committed an additional $1 million in prizemoney for the series, split 60-40 in favour of the series winner or 50-50 if the series is drawn. Australia hold a 1-0 lead coming into the final match. If this lead is preserved at Adelaide Oval, either with victory against New Zealand or a draw, it will see their players share in $600,000.
The prizemoney, either $600,000 or $500,000 in the event of a draw, will be allocated on a pro-rata basis among members of the squads - not just the final 11 - for all three Tests. In the event of a series victory players would receive about $16,000 for each Test. Players who have been in the squad for all three matches will receive pre-tax bonuses of just over $48,000. A series victory against New Zealand, as an opponent ranked outside the top four, would trigger a bonus of just over $14,000, while victory in the final match would deliver an additional $5400.
Meanwhile, Australia's best chance of finally stopping Kane Williamson could rest with the newest member of their Test squad: Steve O'Keefe.
Even though David Warner leads the Trans-Tasman Trophy run tally, New Zealand's Williamson has arguably been the most formidable batsmen of the series in compiling 397 runs at an average of 132.33. Williamson made centuries in the first innings in Brisbane and Perth. It took a borderline leg-before decision to remove him in the second innings at the Gabba, for 59, while at the WACA Ground he was unbeaten on 32 when match finished in a draw.
His ease at scoring has been reflected in Australia's bowlers managing only 11 maiden overs against him among the 560 deliveries he faced.
Williamson's form has led to Peter Siddle saying he would try to "bore" Williamson out at Adelaide Oval, by starving him of scoring opportunities in the hope of triggering a rash shot.
O'Keefe's fine record with the pink ball at Adelaide Oval - he has taken 18 wickets at an average of 18.22 in his three day-night matches at the venue - was a key factor in his inclusion in the squad for the series-ending match.
While the pitch conditions would seemingly count against his inclusion in the final 11, selectors could change their mind if they decide their plans to shackle Williamson are futile.
In the five years since Williamson made his debut a third of his dismissals have come against left-arm finger spinners.
Since Australia named their squad for Adelaide last week coach Darren Lehmann has been adamant that O'Keefe is in contention to play, ahead of one of the three pacemen. If O'Keefe was selected it would be the first time since   January 2006 that Australia have had two specialist spinners in a home Test. Off-spinner Nathan Lyon welcomed that prospect. "We play all formats together ... so we bowl well together," Lyon said.
