BUSH PILOT,
I think you have misunderstood the regs. You may proceed by day to an aerodrome without an approach procedure and/or TAF under the IFR, without providing a suitable alternate, if according to the area forecast, you have the 8 km visibility and no more that 4/8ths cloud below LSALT + 500 for the final route segment.
AIP ENR 1.1 - 73.3.2 a. "not more that SCT cloud is forecast below the final route segment LSALT plus 500FT and forecast visibility at the destination aerodrome is not less than 8 km"
AIP 1.10 - 1.2.1 "... For a flight to a destination for which a prescribed instrument approach precedure does not exist, the minimum requirement is an Area Forecast."
(It would be a bit silly if we could not proceed IFR to an aerodrome without an instrument approach and therefore most likely without a TAF) - there are many small aerodromes without IAPs and TAFs serviced by IFR aircraft.
Hope this makes sense.
