The businessman flew to Far North Queensland on Monday and had been staying at the Cairns Plaza Hotel on the Esplanade.
Mr Brady was reported missing by his family after failing to catch a flight home from his work trip on Thursday.
Police initially traced Mr Brady's movements but the trail went cold after he visited a Caltex service station on Sheridan Street on Wednesday night.
They also searched through drains and thick scrubs 5km from where he was last seen before discovering Mr Brady's suspected body at the Sheridan Street hotel.
Queensland Police confirmed they were treating the death as suspicious and detectives from State Crime Command's Homicide Squad had travelled to Cairns to assist with the investigation.
Acting Detective Inspector Jason Smith said a post mortem examination was being carried out that would 'reveal more information to police' about the death.
'The circumstances of the death appears suspicious at this stage, however we're keeping an open mind.

Inspector Smith said police believe the 32-year-old woman who was pictured could help assist with the investigation and was known to police.
'This female appears to be the last person to have seen Mr Brady alive and we're very keen to speak to her to find out the circumstances, or anything that she might know.
'Currently we feel this woman has some information that would be able to advance the investigation significantly and we'd very much like to speak with her.
'She is only of interest to us at the moment, she is not a suspect,' Inspector Smith said.
