According to Sydney Confidential, the couple have been planning this wedding for a long time now, but have only supplied the most basic details to guests to limit the chances of the location leaking to media.
An insider explained that "guests will be contacted in the morning on the day and given the time and location. I believe it's at night so there will be plenty of time to prepare".
Their wedding invitation included only the date of the service and a note indicating that more details would follow. The couple are expected to contact the guests personally.
Often magazine publishing deals hinge on exclusivity, so Dan and Marni are doing their best to protect their privacy. However, as the source says, "it's getting harder to keep private things private".
Dan plays the role of tattoo tough guy Heath Braxton on the popular nightly soap opera.
