Ali De Winter, Damien Wright and South African pace great Allan Donald are possible candidates to replace Craig McDermott as Cricket Australia's bowling coach.
McDermott made the shock announcement yesterday after just a year in the job, saying he was struggling to balance family life with the demands of touring.
''It has been a very difficult decision,'' McDermott said. ''I felt this to be the right decision from a personal and professional point of view.''
McDermott said he was proud of his role in helping to boost Australia's fast-bowling depth.
The return to form of Ben Hilfenhaus last summer was also partly due to the work of Tasmania's bowling coach De Winter who helped the swing bowler rebuild his career following a poor 2010-11 Ashes campaign.
Donald's cause could be helped by having worked under Australia head coach Mickey Arthur when Arthur was in charge of the South African team.
Former Aussie quick and swing specialist Damien Fleming said Test selector Andy Bichel would also do a good job if available.
Fleming said it was worth having a crack at ex-Test paceman Jason Gillespie (coaching Yorkshire) and former Victoria quick David Saker (England's bowling coach).
''Any of those guys who have been away and shown how good they are, you'd be stupid not to at least ask the question,'' Fleming said. ''Troy Cooley went to England and came back, why couldn't David Saker?
''If Jason Gillespie's the best fast-bowling coach available for Australia then we've got to get him.
''Ali De Winter's name was thrown around a fair bit before Billy [McDermott] got the job so you'd think he'd have to be a good chance.
''Damien Wright was getting rave reviews in Victoria and over there [as New Zealand's bowling coach].''
Fleming said McDermott deserved credit for implementing a simple and effective game plan of bowling full, swinging the ball and attacking the stumps.
''You wouldn't want to mess with that too much coming in,'' Fleming said. ''Just to see James Pattinson come in and swing the ball straight away. Peter Siddle has been such a lion-hearted, hit-the-deck type of bowler. To see him bowling genuine outswingers over the summer is a massive tick for Billy's coaching.'' AAP
