Try giving them something..............like a bullet! turn your tv/radio up or move!
No but really up here in Brisbane there are some set time limits both in time of the day and length to asses if there is a nuisance, so have a check up with your council, you can then be come a whinging pom! though I can say that in over 25yrs working in the UK I can count on one hand the number of complaints from council related to my construction works (not including the greenies) I achieved that in the 1st 6 months here, must still be a throw back from the penal days when we must have got rid of all the whingers along with the other so called undesirables.
Good luck sueoc.
