William Poovey was killed in a train accident last week that also broke Kara's jaw. A freight train crashed into the tourist tram carrying Mr Holmes a Court, US photographer Ms Everett and their wedding party. Twenty people were injured in the smash.

On Thursday, Mr Holmes a Court revealed how the wedding went ahead, with a ceremony in Botswana that was ''smaller and quieter without Will''. In a statement on Facebook, he described Ms Poovey as ''an angel on this earth'' who continued to light up the room with her ''teary smile''.

''Kara requested we rejoin our group in Botswana and gave us Will's camera. She insisted we honour Will by following through with our wedding ceremony and filling the camera with beautiful photographs,'' Mr Holmes a Court said.

''We are thrilled to be married, yet our hearts are broken for the loss of our dear friend.''

Mr Holmes a Court, a Sydney-based businessman and part-owner of the South Sydney Rabbitohs, and Ms Everett both sustained minor injuries in the crash.

''We are OK. Bruised, cut, stitched and strapped. These will fade and heal. Many others were hurt worse than us, and as a group we were very, very lucky,'' Mr Holmes a Court said.

They raised $17,000 for survivors of sexual violence in the Democratic Republic of Congo and say one of the houses will be named in honour of Mr Poovey and his family.

The couple will delay their honeymoon until next year ''when smiles come easier''.

''Good will come from this if we rise to the challenge of living life as Will did: making the most of every day, adding laughter and joy to every room we enter, and deeply loving those close to us,'' Mr Holmes a Court said.

The accident is being investigated by Zimbabwean authorities. Twenty people were reported hurt, including Mr Poovey and two others who survived with injuries.

A friend of Ms Everett told Fairfax Media the tram echoed with screams of terror as it slid more than 250 metres.
