1. Make the crust: Preheat oven to 170°C. In a large bowl, whisk together flour, sugar, and salt. Add golden syrup and melted butter and stir until dough forms. Press mixture into a 9” tart pan with a loose bottom, pressing until the dough is smooth. Prick all over with a fork and bake until golden, 25 to 30 minutes. Let cool completely.
2. Prepare the filling: In a large bowl using a hand mixer or a kitchen whisk, beat the cream until soft peaks form. In another large bowl, beat together the soft cheese and sugar until smooth. Add lemon juice and zest, and vanilla. Beat until combined. Fold in whipped cream, then spoon into cooled tart crust and smooth top.
3. Arrange the sliced strawberries on top of the tart. Heat up the jam with 1-2 tsp of water and brush over the strawberries.
4. Transfer the tart to the fridge and allow it to chill for 2 hours before serving.
