My working holiday visa was revoked at point of entry due to me not informing immigration of criminal record. This was done due to a misunderstanding of what "serious" convictions meant. I now understand that I should have disclosed my record and let them decide if it was serious. My question is as follows: Can I reapply and when?....or am I barred for a specific time period. Will it effect visa application to all countries?

Really appreciate any info that will enlighten me.
