Essential Poll Labor 52% Coalition 48%, page-5

The poll is spread across electorates as part of the normal voting intention poll. They also asked those polled if they had voted in the postal survey. Naturally that aspect of the poll would only reflect the percentages of those polled that had received the Survey and voted. The number would be quite small and on its own could not be taken as being meaningful. What is relevant is the question they put to the whole sample as to whether they would participate in the survey and how would they vote? That provided an overwhelming majority response in favour of the YES vote. At this stage whether by co-incidence or otherwise a small number of those polled who had had received their Survey forms and voted were largely in line with the overall poll response.
