Magpies president Eddie McGuire says De Goey's drink-driving offence amounts to "unacceptable behaviour".
However, he cautioned against overreaction after the incident.
"That's unacceptable behaviour by anybody," McGuire told Triple M on Monday morning.
"You've got to be careful with these things not to overreact, but at the same time get the right result for society, for our club, for everybody associated (with it) and for Jordan."
McGuire conceded De Goey's pattern of indiscretions was concerning, but was hopeful he could turn things around.
"Clearly you do (have concerns). It's like when your kid comes home and they've done something and you go, 'Hang on, what's going on?'. So we'll talk to him," McGuire said.
"Look, Jordie's got a great family and we hope he gets himself right and gets the absolute potential out of his career."
