10 It seems that over a period of more than 70 years, some Judges have been troubled by the subtle distinctions between the meaning of the word or words "know" or "knowledge" or "belief" on the one hand, and "suspect" or "suspicion" on the other. Before I refer to those authorities, I should mention that the ordinary meaning of the word "know" means "be cognisant or aware of; to be acquainted with ... as by sight, experience, or report". The word "knowledge" has a similar meaning. "Belief" means "conviction of the truth or reality of a thing, based upon grounds insufficient to afford positive knowledge". See Macquarie Dictionary.
