·2-min read

Relatives and friends have farewelled the young Brisbane couple and their unborn child killed in a shocking Australia Day crash.

Kate Leadbetter was pregnant when she and her partner Matt Field were struck by an allegedly stolen car driven by a teenager in Alexandra Hills on January 26.

Their families thanked all those who joined them at a private funeral on Monday to say goodbye and the wider community for the support and compassion they received.

"To the first responders and police who looked after Matt, Kate and Miles, and who have supported our families throughout this difficult time, words cannot express the depth of our gratitude for the way you have cared for each and every one of us," the family said in statement said.

"Our families need time together to grieve. Our hearts go out to everyone missing them today, and we thank you for honouring their memories with us."

The families also thanked staff at Iona College who "went to great lengths to help us in farewelling Matt, Kate and Miles today".

In a public statement three days after the crash, the families thanked emergency services, witnesses, and those who left flowers, attended vigils and looked for the couple's lost dog Frankie, for their love and support.

"Our lives have been shattered," the families said a video statement.

"To have lost three cherished members of our families in such a senseless and sudden way is beyond our comprehension."

The couple had built a nursery for Miles "with love and anticipation."

"All children are precious and wonderful in the eyes of their families, but Matt and Kate were truly great human beings, talented and funny and such good company at the happiest point in their lives, about to embark on the thrilling adventure of parenthood," the relatives said.

Police are awaiting legal advice on whether they can also charge the 17-year-old accused of murdering the Brisbane couple over the death of their unborn child.

He allegedly ran a red light and deliberately collided with a truck at an intersection before the 4WD rolled and ploughed into the couple who were crossing the road.

The teen has been remanded to reappear in court by video link in March.
