Probably neither is the answer to your first question.
Interest is normally calculated on a daily basis but depending on account type, none would be calculated on just what is in the account on a fixed date unless maybe a term deposit for a lump sum which has been tied in for the year.
If you lodge a lump sum on 1 Nov you are only going to get 20 days interest and the max lump sum will be 1,000 as that's the monthly max lodgement.
The whole point of this account is to make regular payments and not lump sum.
