Can you provide coordinates for my property boundaries?

In a simple answer, No.

In Queensland property boundaries are not defined by coordinates. The Queensland titling system is based on the Torrens system, which provides certainty of title to land. The Torrens System ensures that a person purchasing land is able to acquire a secure title to that land in a process that facilitates timely and effective land dealings for the community. Under the Torrens Titling system certificate of titles describe land by referring to survey plans. Survey plans do not contain coordinates for property corners. Survey plans define property boundaries by a series of lines of bearings and distances measured by a surveyor with a list of marks that has been placed at each of the boundary corners (usually white pegs).

A surveyors job is to define and/or redefine the land boundaries using the best available evidence for establishing the intention of the parties at the time the boundaries were created and the greatest weight must always be given to lines and corners marked on the ground.

Therefore it is the survey marks that define your property boundaries, not coordinates.

Many maps are produced that show coordinates on them. Sometimes the property boundaries are plotted or overlaid onto these maps. These maps merely provide a representation of where the boundaries might be, and are approximate only. It is also important to note that handheld GPS are not accurate in terms of repeatability and reliability (usually +-10m). In urban areas this means by using approximate coordinates and a handheld GPS you could be on your neighbour's lot! If you live on a rural property, sometimes approximate GPS coordinates from a map overlay may assist you in locating any visible survey marks at your property corners. However keep in mind that TerraModus Surveying have performed rural surveys where the boundary overlay on maps were hundreds of metres out of position. 

You may see surveyors use survey-grade GPS (millimetre accuracy with reliabilty). GPS is a great tool for surveyors but for most urban cadastral surveys, GPS is not suitable for boundary measurements and that is why you see surveyors using total stations to accurately measure bearings (angles) and distances.
