Despite going a goal down against the run of play courtesy of Adam Spear's 13th minute goal, the Millers battled back with Brogan pulling the strings as he crossed for Ryan Taylor to level on 27 minutes.
Brogan got on the scoresheet himself with 13 minutes left, cutting in to curl home a 20 yard right foot shot before the Magpies pulled a goal back six minutes from time.
